Description

FUSED BICYCLIC COMPOUNDS FOR THE TREATMENT OF DISEASE CROSS-REFERENCE

[0001] This application claims the benefit of U.S. provisional application Ser. No. 62/083,031, filed November 21, 2014, which is incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

[0002] Farnesoid X receptor (FXR) is a member of the nuclear hormone receptor superfamily of ligand-activated transcription factors. Bile acids are FXR physiological ligands. On activation by bile acids, FXR regulates a wide variety of target genes that are critically involved in the control of bile acid, lipid and glucose homeostasis. Thus, FXR plays a key role in the pathogenesis of cholestatic diseases, non-alcoholic fatty liver disease and inflammatory bowel disease.

DETAILED DESCRIPTION OF THE INVENTION

[0029] The Farnesoid X receptor (FXR; also referred to as NR1H4; nuclear receptor nomenclature committee 1999) is a member of the steroid and thyroid hormone nuclear receptor superfamily of ligand regulated transcription factors. FXR is highly expressed in the liver, kidney, intestines and the adrenals and at lower levels in the vasculature (Forman et al., Cell 1995, 81(5):687-93). Bile acids, the end-products of cholesterol catabolism, bind directly to the ligand binding pocket of FXR and act as agonists to increase the receptor's ability to activate transcription (Makishima et al., Science 1999, 284(5418):1362-5 1999; Mi et al., Mol Cell 2003, 11(4):1093-100; Parks et al., Science 1999, 284(5418):1365-8; Wang et al., Mol Cell 1999, 3(5):543-53). In response to bile acid binding FXR regulates a network of genes that control the synthesis, transport, and catabolism of bile acids, but also triglycerides and cholesterol (Chawla et al., Cell 2000, 103(1):1-4; Repa and Mangelsdorf, Annu Rev Cell Dev Biol 2000, 16:459-81). Thus FXR functions as a regulator of lipid metabolism by modifying gene expression in response to quantitative changes in the metabolism and breakdown of cholesterol. In support of this conclusion, studies in humans and in animals have demonstrated that modifying bile acid levels can have profound effects on plasma triglyceride and cholesterol levels (Angelin et al., J Lipid Res 1978, 19(8):1017-24; Bateson et al., Br J Clin Pharmacol 1978, 5(3):249-54; Iser and Sali, Drugs 1981, 21(2):90-119; Kuroki et al., Lipids 1999, 34(8):817-23).

[0030] Metabolic disease including obesity, diabetes, hypertension, and cardiovascular disease, are diseases driven by both mulitfactorial genetics (thrifty genotypes) as well as lifestyle habits, and are now reaching epidemic proportions in developed nations. It is believed that increasingly high caloric diets combined with sedentary life styles are major contributors to the growing incidence of these diseases. Importantly hyperlipidemia is associated with many types of metabolic disease, and statistics from the American Heart Association indicate that approximately half of the adult population in the United States has plasma cholesterol levels that put individuals at risk for the development of cardiovascular disease (American Heart Association, Heart disease and stroke statistics - 2005 update; 2005:1-59). Furthermore, the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III; ATPIII, National Cholesterol Education Program 2001) has identified elevated triglyceride levels as an independent risk factor for the development of cardiovascular disease. Approximately one third of the adult population in the United States that have elevated cholesterol levels also have increased triglycerides. The elevation in plasma triglycerides has now been recognized as an early and dominant dyslipidemic symptom in patients with obesity, metabolic syndrome and diabetes and has been suggested to play a causative role in the development of insulin resistance and type II diabetes (Hegarty et al., Acta Physiol Scand 2003;178(4):373-83; Shulman, J Clin Invest 2000;106(2):171-6).

[0031] Current standard of care for hyperlipidemia focuses on lowering low density lipoprotein cholesterol (LDL) using the statin class of hydroxymethy-glutaryl-CoA reductase inhibitors (National Cholesterol Education Program 2001). However, even after statin therapy a significant number of patients still exhibit elevated levels of plasma triglycerides and triglyceride-rich lipoproteins including very low density lipoproteins (VLDL) and intermediate density lipoproteins (IDL) (Friday, Exp Biol Med (Maywood) 2003, 228(7):769-78; Quilliam et al., J Manag Care Pharm 2004, 10(3):244-50). To treat this population of patients with concurrent high plasma triglyceride levels the ATPIII has identified lowering of triglyceride-rich cholesterol fractions (VLDL + IDL) as a secondary target of drug therapy (National Cholesterol Education Program 2001). Unfortunately treatment of such patients with fibrates, an approved class of triglyceride lowering drugs, has potential adverse side effects, including the possibility of increased LDL cholesterol as well as carrying the risk of fatal rhabdomyolysis, so that combination therapy must proceed cautiously (National Cholesterol Education Program 2001). Similarly nicotinic acid, a second approved triglyceride lowering agent, is contraindicated in patients with insulin resistance and type II diabetes (Capuzzi et al., Curr Atheroscler Rep 2000, 2(1):64-71). Taken together these observations highlight the need for an effective therapeutic agent for the lowering of triglycerides and non-HDL cholesterol in patients with cardiovascular disease, diabetes, and metabolic syndrome.

[0032] The maintenance of lipid homeostasis requires coordinate control of cholesterol and triglyceride synthesis, transport, up-take, and excretion. Interestingly, studies in human and in animal models have uncovered a link between bile acids, the metabolic end-product of cholesterol metabolism, and lipid homeostasis. Clinical studies in the late 1970s exploring the effect of bile acids on cholesterol gallstones demonstrated that treatment with chenodeoxycholic acid (CDCA) reduces plasma triglyceride levels (Bateson et al., Br J Clin Pharmacol 1978, 5(3):249-54; Iser and Sali, Drugs 1981, 21(2):90-119). In contrast, treatment with bile acid sequestrants, which deplete intestinal bile acids, increase triglycerides (Angelin et al., J Lipid Res 1978;19(8):1017-24). Importantly the bile acid-dependent decrease in triglycerides is mediated, at least in part, through a reduction in the production of VLDL (Hirokane et al., J Biol Chem 2004, 279(44):45685-92; Post et al., Arterioscler Thromb Vase Biol 2004, 24(4):768-74; Sirvent et al., FEBS Lett 2004, 566(1-3):173-7; Kang and Davis, Biochim Biophys Acta 2000, 1529(1-3):223-30). While bile acids are known to mediate the absorption of cholesterol and fat in the intestine the mechanistic basis for the connection between bile acids and lipid levels remained unclear until the recent characterization of FXR.

[0033] The FXR was originally cloned and classified as an orphan member of the nuclear hormone receptor superfamily based upon DNA sequence homology. Initial studies identified farnesol as a ligand for FXR (Forman et al., Cell 1995, 81(5):687-93), however, subsequent analysis demonstrated that bile acids bind directly to the ligand binding domain of FXR and function as activators of the receptor's transcriptional activity. The binding affinities of bile acids for FXR is near the concentration that these compounds reach in animals (gM) lending support to the idea that bile acids function as endogenous ligands in vivo (Makishima et al., Science 1999, 284(5418):1362-5 1999; Mi et al., Mol Cell 2003, 11(4):1093-100; Parks et al., Science 1999, 284(5418):1365-8; Wang et al., Mol Cell 1999, 3(5):543-53). Activation of FXR upon bile acid binding leads to transcriptional down-regulation of cholesterol 7a-hydroxylase (CYP7A1), the rate limiting enzyme in the conversion of cholesterol to bile acids. Inhibition of CYP7A1 by bile acids occurs via FXR-dependent induction of the small heterodimeric partner (SHP; also referred to as NROB2, Nuclear Receptor Nomenclature Committee 1999), a transcriptional repressor. Binding sites for FXR have been identified in the SHP promoter indicating that this gene is a direct target of FXR (Lu et al., Mol Cell 2000, 6(3):507-15; Goodwin et al., Mol Cell 2000, 6(3):517-26). Thus bile acid-dependent repression of CYP7A1 is indirect and results from a transcriptional cascade initiated by FXR. A similar SHP-dependent mechanism has been described for the bile acid repression of another gene involved in bile acid synthesis, CYP8B1 (sterol 12a hydroxylase; Yang et al., Biochim Biophys Acta 2002, 1583(1):63-73), and for the sodium/taurocholate cotransporter peptide (NTCP) which is one of two major transporters responsible for bile acid up-take by the liver (Denson et al., Gastroenterology 2001;121(1):140-7). In contrast the genes encoding the bile salt export pump (BSEP) and the multidrug resistance protein 2 (MDR2) are directly induced by FXR, once again via binding sites in their respective promoter regions (Ananthanarayanan et al., J Biol Chem 2001, 276(31):28857-65; Huang et al., J Biol Chem 2003, 278(51):51085-90; Liu et al., J Clin Invest 2003, 112(11):1678-87). These two transporters are required for the transfer of bile acids (BSEP) and phospholipids (MDR2) out of the hepatocytes into the biliary system. This pattern of FXR-dependent gene expression defines a classic feedback loop where high levels of bile acids inhibit new bile acid synthesis and bile acid uptake while simultaneously promoting their own clearance.

[0034] The regulation of bile acid synthesis and transport by FXR has important implications for cholesterol metabolism. Repression of CYP7A1 and CYP8B1 impacts the bile acid synthetic pathway at two important points. First, inhibition of CYP7A1, the rate limiting enzyme, can decrease synthesis and reduce the size of the bile acid pool. Second, inhibition of CYP8B1 alters bile acid composition by favoring the production of more hydrophilic bile acids such as CDCA (muricholic acid/MCA in mice) (Russell, Annu Rev Biochem 2003, 72:137-74). Importantly, studies in mice have demonstrated that the more hydrophilic bile acids are less efficient at promoting intestinal cholesterol absorption (Wang et al., Am J Physiol Gastrointest Liver Physiol 2003, 285(3):G494-502).

[0035] Although regulating bile acid synthesis may contribute to the FXR-dependent effects on lipid metabolism, gene expression analysis indicates that FXR also directly influences triglyceride synthesis and VLDL production. FXR agonists induce the genes encoding fibroblast growth factor 19 (Holt et al., Genes Dev 2003, 17(13):1581-91), acylation stimulating protein (a proteolytic product of complement C3; Li et al., J Biol Chem 2005, 280(9):7427-34), apolipoprotein CII (Kast et al., Mol Endocrinol 2001, 15(10):1720-8), and apolipoprotein AV (Prieur et al., J Biol Chem 2003, 278(28):25468-80) all of which are known to promote the clearance and oxidation of fat carried by triglyceride rich lipoproteins. Additionally FXR inhibits expression of the genes encoding apolipoprotein CIII (Claudel et al., Gastroenterology 2003, 125(2):544-55), an inhibitor of lipoprotein lipase, and the sterol response element binding protein I (SREBPlc; Watanabe et al., J Clin Invest 2004, 113(10):1408-18). SREBPlc, a member of basic helix-loop-helix family of transcription factors, functions as a master transcriptional regulator of the enzymes required for fatty acid synthesis (Osborne, J Biol Chem 2000, 275(42):32379-82). Taken together the genetic network controlled by FXR defines a signal transduction system poised to respond to changes in fat and carbohydrate dietary intake-driven lipid homeostasis. High levels of cholesterol in the liver will lead to increased production of bile acids and subsequent activation of FXR. In response to this activating signal FXR decreases the absorption of cholesterol in the intestine, favoring excretion, increases the clearance and oxidation of triglycerides and decreases the synthesis of fatty acids leading to a reduction in VLDL production.

[0036] The ability of FXR to regulate bile-acid synthesis, clearance and homeostasis as supported by the ability of FXR ligands to promote the transport of bile acid and phospholipids out of the liver suggests a utility for such compounds in diseases of disturbed bile acid and cholesterol flow such as Primary Biliary cirrhosis and NASH. In this regard FXR agonists have been shown to be effective in animal models of cholestasis, gallstones, and liver fibrosis (Liu et al., J Clin Invest 2003, 112(11):1678-87; Fiorocci et al., Gastroenterology 2004, 127(5):1497 512; Fiorocci et al., J Pharmacol Exp Ther 2005, 313(2):604-12; Fiorocci et al., J Pharmacol Exp Ther 2005, 314(2):584-95).

[00198] In some embodiments, compounds described herein are prepared as prodrugs. A "prodrug" refers to an agent that is converted into the parent drug in vivo. Prodrugs are often

useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. In some embodiments, the design of a prodrug increases the effective water solubility. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharmaceutically or therapeutically active form of the compound.

[00199] Prodrugs of the compounds described herein include, but are not limited to, esters, ethers, carbonates, thiocarbonates, N-acyl derivatives, N-acyloxyalkyl derivatives, quaternary derivatives of tertiary amines, N-Mannich bases, Schiff bases, amino acid conjugates, phosphate esters, and sulfonate esters. See for example Design of Prodrugs, Bundgaard, A. Ed., Elseview, 1985 and Method in Enzymology, Widder, K. et al., Ed.; Academic, 1985, vol. 42, p. 309-396; Bundgaard, H. "Design and Application of Prodrugs" in A Textbook of Drug Design and Development, Krosgaard-Larsen and H. Bundgaard, Ed., 1991, Chapter 5, p. 113-191; and Bundgaard, H., Advanced Drug Delivery Review, 1992, 8, 1-38, each of which is incorporated herein by reference. In some embodiments, a hydroxyl group in the compounds disclosed herein is used to form a prodrug, wherein the hydroxyl group is incorporated into an acyloxyalkyl ester, alkoxycarbonyloxyalkyl ester, alkyl ester, aryl ester, phosphate ester, sugar ester, ether, and the like.

[00200] Prodrug forms of the herein described compounds, wherein the prodrug is metabolized in vivo to produce a compound of Formula (I), (II), (III), (II1a), (IV), (IVa), (V), (Va), (VI), (VIa), (VII), (VIII), (IX), (IXa), (X), or (Xa), as set forth herein are included within the scope of the claims. In some cases, some of the herein-described compounds may be a prodrug for another derivative or active compound.

[00201] In specific embodiments, the compounds described herein exist in solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. In other embodiments, the compounds described herein exist in unsolvated form.

[00202] In some embodiments, the compounds of Formula (I), (II), (III), (II1a), (IV), (IVa), (V), (Va), (VI), (VIa), (VII), (VIII), (IX), (IXa), (X), or (Xa) described herein include solvent addition forms or crystal forms thereof, particularly solvates or polymorphs. Solvates contain either stoichiometric or non-stoichiometric amounts of a solvent, and may be formed during the process of crystallization with pharmaceutically acceptable solvents such as water, ethanol, and the like. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is alcohol.

[00203] In some embodiments, sites on the compounds of Formula (I), (II), (III), (II1a), (IV), (IVa), (V), (Va), (VI), (VIa), (VII), (VIII), (IX), (IXa), (X), or (Xa) disclosed herein are susceptible to various metabolic reactions. Therefore incorporation of appropriate substituents at the places of metabolic reactions will reduce, minimize or eliminate the metabolic pathways. In specific embodiments, the appropriate substituent to decrease or eliminate the susceptibility of the aromatic ring to metabolic reactions is, by way of example only, a halogen, deuterium or an alkyl group.

[00204] In some embodiments, the compounds of Formula (I), (II), (III), (II1a), (IV), (IVa), (V), (Va), (VI), (VIa), (VII), (VIII), (IX), (IXa), (X), or (Xa) disclosed herein are isotopically labeled, which are identical to those recited in the various formulae and structures presented herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. In some embodiments, one or more hydrogen atoms are replaced with deuterium. In some embodiments, metabolic sites on the compounds described herein are deuterated. In some embodiments, substitution with deuterium affords certain therapeutic advantages resulting from greater metabolic stability, such as, for example, increased in vivo half-life or reduced dosage requirements.

[00205] In some embodiments, compounds described herein, such as compounds of Formula (I), (II), (III), (II1a), (IV), (IVa), (V), (Va), (VI), (VIa), (VII), (VIII), (IX), (IXa), (X), or (Xa), are in various forms, including but not limited to, amorphous forms, milled forms and nano particulate forms. In addition, compounds described herein include crystalline forms, also known as polymorphs. Polymorphs include the different crystal packing arrangements of the same elemental composition of a compound. Polymorphs usually have different X-ray diffraction patterns, melting points, density, hardness, crystal shape, optical properties, stability, and solubility. Various factors such as the recrystallization solvent, rate of crystallization, and storage temperature may cause a single crystal form to dominate.

[00206] The screening and characterization of the pharmaceutically acceptable salts, polymorphs and/or solvates may be accomplished using a variety of techniques including, but not limited to, thermal analysis, x-ray diffraction, spectroscopy, vapor sorption, and microscopy. Thermal analysis methods address thermo chemical degradation or thermo physical processes including, but not limited to, polymorphic transitions, and such methods are used to analyze the relationships between polymorphic forms, determine weight loss, to find the glass transition temperature, or for excipient compatibility studies. Such methods include, but are not limited to, Differential scanning calorimetry (DSC), Modulated Differential Scanning Calorimetry (MDCS), Thermogravimetric analysis (TGA), and Thermogravi-metric and Infrared analysis (TG/IR). X-ray diffraction methods include, but are not limited to, single crystal and powder diffractometers and synchrotron sources. The various spectroscopic techniques used include, but are not limited to, Raman, FTIR, UV-VIS, and NMR (liquid and solid state). The various microscopy techniques include, but are not limited to, polarized light microscopy, Scanning Electron Microscopy (SEM) with Energy Dispersive X-Ray Analysis (EDX), Environmental Scanning Electron Microscopy with EDX (in gas or water vapor atmosphere), IR microscopy, and Raman microscopy.

Use of Protecting Groups

[00211] In the reactions described, it maybe necessary to protect reactive functional groups, for example hydroxy, amino, imino, thio or carboxy groups, where these are desired in the final product, in order to avoid their unwanted participation in reactions. Protecting groups are used to block some or all of the reactive moieties and prevent such groups from participating in chemical reactions until the protective group is removed. It is preferred that each protective group be removable by a different means. Protective groups that are cleaved under totally disparate reaction conditions fulfill the requirement of differential removal.

[00212] Protective groups can be removed by acid, base, reducing conditions (such as, for example, hydrogenolysis), and/or oxidative conditions. Groups such as trityl, dimethoxytrityl, acetal and t-butyldimethylsilyl are acid labile and may be used to protect carboxy and hydroxy reactive moieties in the presence of amino groups protected with Cbz groups, which are removable by hydrogenolysis, and Fmoc groups, which are base labile. Carboxylic acid and hydroxy reactive moieties may be blocked with base labile groups such as, but not limited to, methyl, ethyl, and acetyl in the presence of amines blocked with acid labile groups such as t butyl carbamate or with carbamates that are both acid and base stable but hydrolytically removable.

[00213] Carboxylic acid and hydroxy reactive moieties may also be blocked with hydrolytically removable protective groups such as the benzyl group, while amine groups capable of hydrogen bonding with acids may be blocked with base labile groups such as Fmoc. Carboxylic acid reactive moieties may be protected by conversion to simple ester compounds as exemplified herein, which include conversion to alkyl esters, or they may be blocked with oxidatively removable protective groups such as 2,4-dimethoxybenzyl, while co-existing amino groups may be blocked with fluoride labile silyl carbamates.

[00214] Allyl blocking groups are useful in then presence of acid- and base- protecting groups since the former are stable and can be subsequently removed by metal or pi-acid catalysts. For example, an allyl-blocked carboxylic acid can be deprotected with a Pd°-catalyzed reaction in the presence of acid labile t-butyl carbamate or base-labile acetate amine protecting groups. Yet another form of protecting group is a resin to which a compound or intermediate may be attached. As long as the residue is attached to the resin, that functional group is blocked and cannot react. Once released from the resin, the functional group is available to react.

[00215] Typically blocking/protecting groups may be selected from:

The alkyl group of the compounds described herein may be designated as "C1 -C 6 alkyl" or similar designations. By way of example only, "C 1-C 6 alkyl" indicates that there are one to six carbon atoms in the alkyl chain, i.e., the alkyl chain is selected from the group consisting of methyl, ethyl, n-propyl, iso propyl, n-butyl, iso-butyl, sec-butyl, t-butyl, n-pentyl, iso-pentyl, neo-pentyl, hexyl, propen-3-yl (allyl), cyclopropylmethyl, cyclobutylmethyl, cyclopentylmethyl, cyclohexylmethyl. Alkyl groups can be substituted or unsubstituted. Depending on the structure, an alkyl group can be a monoradical or a diradical (i.e., an alkylene group).

[00226] An "alkoxy" refers to a "-O-alkyl" group, where alkyl is as defined herein.

[00227] The term "alkenyl" refers to a type of alkyl group in which two atoms of the alkyl group form a double bond that is not part of an aromatic group. Non-limiting examples of an alkenyl group include -CH=CH 2, -C(CH 3)=CH 2 , -CH=CHCH 3, -CH=C(CH 3) 2 and C(CH 3)=CHCH 3 . The alkenyl moiety may be branched, straight chain, or cyclic (in which case, it would also be known as a "cycloalkenyl" group). Alkenyl groups may have 2 to 6 carbons. Alkenyl groups can be substituted or unsubstituted. Depending on the structure, an alkenyl group can be a monoradical or a diradical (i.e., an alkenylene group).

[00228] The term "alkynyl" refers to a type of alkyl group in which the two atoms of the alkyl group form a triple bond.

[00245] The methods and formulations described herein include the use of crystalline forms (also known as polymorphs), or pharmaceutically acceptable salts of compounds having the structure of Formula (I), (II), (III), (II1a), (IV), (IVa), (V), (Va), (VI), (VIa), (VII), (VIII), (IX), (IXa), (X), or (Xa), as well as active metabolites of these compounds having the same type of activity.

[00246] As used herein, the term "about" or "approximately" means within 20%, preferably within 10%, and more preferably within 5% of a given value or range.

[00247] The term a "therapeutically effective amount" as used herein refers to the amount of an FXR modulator that, when administered to a mammal in need, is effective to at least partially ameliorate or to at least partially prevent diseases, disorders or conditions described herein.

[00248] As used herein, the term "expression" includes the process by which polynucleotides are transcribed into mRNA and translated into peptides, polypeptides, or proteins.

[00249] The term "activator" is used in this specification to denote any molecular species that results in activation of the indicated receptor, regardless of whether the species itself binds to the receptor or a metabolite of the species binds to the receptor when the species is administered topically. Thus, the activator can be a ligand of the receptor or it can be an activator that is metabolized to the ligand of the receptor, i.e., a metabolite that is formed in tissue and is the actual ligand.

[00250] The term "antagonist" as used herein, refers to a small -molecule agent that binds to a nuclear hormone receptor and subsequently decreases the agonist induced transcriptional activity of the nuclear hormone receptor.

[00251] The term "agonist" as used herein, refers to a small-molecule agent that binds to a nuclear hormone receptor and subsequently increases nuclear hormone receptor transcriptional activity in the absence of a known agonist.

[00252] The term "inverse agonist" as used herein, refers to a small-molecule agent that binds to a nuclear hormone receptor and subsequently decreases the basal level of nuclear hormone receptor transcriptional activity that is present in the absence of a known agonist.

Furthermore, in other embodiments, the drug is delivered in a targeted drug delivery system, for example, in a liposome coated with organ-specific antibody. In such embodiments, the liposomes are targeted to and taken up selectively by the organ. In yet other embodiments, the compound as described herein is provided in the form of a rapid release formulation, in the form of an extended release formulation, or in the form of an intermediate release formulation. In yet other embodiments, the compound described herein is administered topically.

Pharmaceutical compositions and methods of administration of FXR modulators

[00259] Administration of FXR modulators as described herein can be in any pharmacological form including a therapeutically effective amount of an FXR modulator alone or in combination with a pharmaceutically acceptable carrier.

[00260] Pharmaceutical compositions may be formulated in a conventional manner using one or more physiologically acceptable carriers including excipients and auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen. Additional details about suitable excipients for pharmaceutical compositions described herein may be found, for example, in Remington: The Science and Practice of Pharmacy, Nineteenth Ed (Easton, Pa.: Mack Publishing Company, 1995); Hoover, John E., Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pennsylvania 1975; Liberman, H.A. and Lachman, L., Eds., Pharmaceutical Dosage Forms, Marcel Decker, New York, N.Y., 1980; and Pharmaceutical Dosage Forms and Drug Delivery Systems, Seventh Ed. (Lippincott Williams & Wilkins1999), herein incorporated by reference for such disclosure.

[00261] A pharmaceutical composition, as used herein, refers to a mixture of a compound of Formula (I), (II), (III), (II1a), (IV), (IVa), (V), (Va), (VI), (VIa), (VII), (VIII), (IX), (IXa), (X), or (Xa) described herein, with other chemical components, such as carriers, stabilizers, diluents, dispersing agents, suspending agents, thickening agents, and/or excipients. The pharmaceutical composition facilitates administration of the compound to an organism. In practicing the methods of treatment or use provided herein, therapeutically effective amounts of compounds described herein are administered in a pharmaceutical composition to a mammal having a disease, disorder, or condition to be treated. In some embodiments, the mammal is a human. A therapeutically effective amount can vary widely depending on the severity of the disease, the age and relative health of the subject, the potency of the compound used and other factors. The compounds of Formula (I), (II), (III), (II1a), (IV), (IVa), (V), (Va), (VI), (VIa), (VII), (VIII), (IX), (IXa), (X), or (Xa) can be used singly or in combination with one or more therapeutic agents as components of mixtures (as in combination therapy).

[00262] The pharmaceutical formulations described herein can be administered to a subject by multiple administration routes, including but not limited to, oral, parenteral (e.g., intravenous, subcutaneous, intramuscular), intranasal, buccal, topical, rectal, or transdermal administration routes. Moreover, the pharmaceutical compositions described herein, which include a compound of Formula (I), (II), (III), (II1a), (IV), (IVa), (V), (Va), (VI), (VIa), (VII), (VIII), (IX), (IXa), (X), or (Xa) described herein, can be formulated into any suitable dosage form, including but not limited to, aqueous oral dispersions, liquids, gels, syrups, elixirs, slurries, suspensions, aerosols, controlled release formulations, fast melt formulations, effervescent formulations, lyophilized formulations, tablets, powders, pills, dragees, capsules, delayed release formulations, extended release formulations, pulsatile release formulations, multiparticulate formulations, and mixed immediate release and controlled release formulations.

[00263] Pharmaceutical compositions including a compound described herein may be manufactured in a conventional manner, such as, by way of example only, by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or compression processes.

[00264] Dose administration can be repeated depending upon the pharmacokinetic parameters of the dosage formulation and the route of administration used.

[00265] It is especially advantageous to formulate compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the mammalian subjects to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms are dictated by and directly dependent on (a) the unique characteristics of the FXR modulator and the particular therapeutic effect to be achieved and (b) the limitations inherent in the art of compounding such an active compound for the treatment of sensitivity in individuals. The specific dose can be readily calculated by one of ordinary skill in the art, e.g., according to the approximate body weight or body surface area of the patient or the volume of body space to be occupied. The dose will also be calculated dependent upon the particular route of administration selected. Further refinement of the calculations necessary to determine the appropriate dosage for treatment is routinely made by those of ordinary skill in the art. Such calculations can be made without undue experimentation by one skilled in the art in light of the FXR modulator activities disclosed herein in assay preparations of target cells. Exact dosages are determined in conjunction with standard dose-response studies. It will be understood that the amount of the composition actually administered will be determined by a practitioner, in the light of the relevant circumstances including the condition or conditions to be treated, the choice of composition to be administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the chosen route of administration.

[00266] Toxicity and therapeutic efficacy of such FXR modulators can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, for example, for determining the LD 5 0 (the dose lethal to 50% of the population) and the ED5 0 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio LD5 0 /ED5 0 . FXR modulators that exhibit large therapeutic indices are preferred. While FXR modulators that exhibit toxic side effects may be used, care should be taken to design a delivery system that targets such modulators to the site of affected tissue in order to minimize potential damage to uninfected cells and, thereby, reduce side effects.

[00267] The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such FXR modulators lies preferably within a range of circulating concentrations that include the ED5 0 with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. For any FXR modulator used in a method described herein, the therapeutically effective dose can be estimated initially from cell culture assays. A dose may be formulated in animal models to achieve a circulating plasma concentration range that includes the IC5 0 (i.e., the concentration of FXR modulator that achieves a half-maximal inhibition of symptoms) as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma may be measured, for example, by high performance liquid chromatography. Methods of Dosing and Treatment Regimens

[00268] The compounds described herein can be used in the preparation of medicaments for the modulation of FXR, or for the treatment of diseases or conditions that would benefit, at least in part, from modulation of FXR. In addition, a method for treating any of the diseases or conditions described herein in a subject in need of such treatment, involves administration of pharmaceutical compositions containing at least one compound described herein, or a pharmaceutically acceptable salt, or pharmaceutically acceptable solvate or hydrate thereof, in therapeutically effective amounts to said subject.

[00269] The compositions containing the compound(s) described herein can be administered for prophylactic and/or therapeutic treatments. In therapeutic applications, the compositions are administered to a patient already suffering from a disease or condition, in an amount sufficient to cure or at least partially arrest the symptoms of the disease or condition. Amounts effective for this use will depend on the severity and course of the disease or condition, previous therapy, the patient's health status, weight, and response to the drugs, and the judgment of the treating physician.

[00270] In prophylactic applications, compositions containing the compounds described herein are administered to a patient susceptible to or otherwise at risk of a particular disease, disorder or condition. Such an amount is defined to be a "prophylactically effective amount or dose." In this use, the precise amounts also depend on the patient's state of health, weight, and the like. When used in a patient, effective amounts for this use will depend on the severity and course of the disease, disorder or condition, previous therapy, the patient's health status and response to the drugs, and the judgment of the treating physician.

[00271] In the case wherein the patient's condition does not improve, upon the doctor's discretion the administration of the compounds may be administered chronically, that is, for an extended period of time, including throughout the duration of the patient's life in order to ameliorate or otherwise control or limit the symptoms of the patient's disease or condition.

[00272] In the case wherein the patient's status does improve, upon the doctor's discretion the administration of the compounds may be given continuously; alternatively, the dose of drug being administered may be temporarily reduced or temporarily suspended for a certain length of time (i.e., a "drug holiday"). The length of the drug holiday can vary between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, 35 days, 50 days, 70 days, 100 days, 120 days, 150 days, 180 days, 200 days, 250 days, 280 days, 300 days, 320 days, 350 days, or 365 days. The dose reduction during a drug holiday may be from about 10% to about 100%, including, by way of example only, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, or about 100%.

[00273] Once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, the dosage or the frequency of administration, or both, can be reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. Patients can, however, require intermittent treatment on a long term basis upon any recurrence of symptoms.

[00274] The amount of a given agent that will correspond to such an amount will vary depending upon factors such as the particular compound, disease or condition and its severity, the identity (e.g., weight) of the subject or host in need of treatment, but can nevertheless be determined in a manner recognized in the field according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, the condition being treated, and the subject or host being treated. In general, however, doses employed for adult human treatment will typically be in the range of about 0.01 mg per day to about 5000 mg per day, in some embodiments, about 1 mg per day to about 1500 mg per day. The desired dose may conveniently be presented in a single dose or as divided doses administered simultaneously (or over a short period of time) or at appropriate intervals, for example as two, three, four or more sub-doses per day.

[00275] The pharmaceutical composition described herein may be in unit dosage forms suitable for single administration of precise dosages. In unit dosage form, the formulation is divided into unit doses containing appropriate quantities of one or more compound. The unit dosage may be in the form of a package containing discrete quantities of the formulation. Non-limiting examples are packaged tablets or capsules, and powders in vials or ampoules. Aqueous suspension compositions can be packaged in single-dose non-reclosable containers. Alternatively, multiple-dose reclosable containers can be used, in which case it is typical to include a preservative in the composition. By way of example only, formulations for parenteral injection may be presented in unit dosage form, which include, but are not limited to ampoules, or in multi-dose containers, with an added preservative.

[00276] The daily dosages appropriate for the compounds described herein described herein are from about 0.001 mg/kg to about 30 mg/kg. In one embodiment, the daily dosages are from about 0.01 mg/kg to about 10 mg/kg. An indicated daily dosage in the larger mammal, including, but not limited to, humans, is in the range from about 0.1 mg to about 1000 mg, conveniently administered in a single dose or in divided doses, including, but not limited to, up to four times a day or in extended release form. Suitable unit dosage forms for oral administration include from about 1 to about 500 mg active ingredient. In one embodiment, the unit dosage is about 1 mg, about 5 mg, about, 10 mg, about 20 mg, about 50 mg, about 100 mg, about 200 mg, about 250 mg, about 400 mg, or about 500 mg. The foregoing ranges are merely suggestive, as the number of variables in regard to an individual treatment regime is large, and considerable excursions from these recommended values are not uncommon. Such dosages may be altered depending on a number of variables, not limited to the activity of the compound used, the disease or condition to be treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the practitioner.

[00277] Toxicity and therapeutic efficacy of such therapeutic regimens can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between the toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio between LD5 0 and ED5 0 . Compounds exhibiting high therapeutic indices are preferred. The data obtained from cell culture assays and animal studies can be used in formulating a range of dosage for use in human. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED 50 with minimal toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized.

Example 50: FXR Agonist Assay

[003261 Starting from 3.33 mM ofcompound inDMSO0solution,a 10-point 3-fold serial dilution was made by diluting 5pL of compound into 10pL ofDMS. The serially diluted compound was then diluted 1:33 into DMEM. This medium was then diluted ten-fold into the culture medium with the cells (10 pL/well). All concentration points are assayed in duplicate. Plateswereincubatedat37°Cfor20hours.Aftertheincubation,20Lofculturemedium were removed from each well and mixed with 50L ofassay solution (PierceTMGaussia Luciferase Flash Assay Kit). The luminescence was measured immediately after addition of the Luc substrate with an Envision microplate reader. The raw data was uploaded to CDD and dose response curves were generated using the Levenberg-Marquardt algorithm integrated into CDD. A negative controlDMSO0is included on each plate and used to normalize the data with the CDD built-in normalization function. The EC50Odata for the assay is shown in Table 1. Table 1
